UV-P Application scenarios

1. Polyvinyl Chloride (PVC) Products:

Used in PVC films, pipes, sheets, profiles, etc., to prevent degradation, discoloration, and embrittlement caused by UV radiation, extending their service life.

2. Polyester-related Materials:

Suitable for polyester resins, polyester fibers, chlorine-containing polyesters, etc., improving the weather resistance of fabrics, containers, films, etc., made from these materials.

3. Polystyrene (PS) and its Copolymers:

Used in polystyrene plastics, AS resins, etc., to prevent yellowing and performance degradation caused by UV light, especially suitable for transparent products.

4. Polycarbonate (PC) Products:

Used in PC sheets, PC plastic parts, etc., to protect the transparency and mechanical properties of the material and prevent aging caused by UV light.

5. Polymethyl Methacrylate (PMMA, Acrylic Glass):

Effectively slows down aging, cracking, and decreased light transmittance of acrylic glass during outdoor use.

6. ABS Resin Products:

Applied to electrical casings, automotive parts, etc., made of ABS plastic, enhancing their weather resistance and extending their service life.

7. Epoxy Resin-related Products:

Used in epoxy resin adhesives, coatings, composite materials, etc., to improve the stability of products in outdoor environments.

8. Acrylic Resins:

Suitable for acrylic resin coatings, acrylic products, etc., preventing discoloration and chalking caused by UV radiation.

9. Unsaturated Resin Products:

Used in fiberglass, artificial stone, etc., made from unsaturated polyester resins, enhancing their aging resistance.

10. Cellulose Resins:

Such as cellulose acetate, can be used as a UV absorber for these resins, protecting related products.

11. Elastomers and Adhesives:

Used in various elastomer materials and adhesive products to improve their UV aging resistance and ensure stable product performance.

12. Food Contact Plastic Products:

Because they meet relevant safety standards, they can be used in the production of plastic containers, packaging materials, etc., that come into contact with food, preventing material aging from affecting food safety.

13. Cosmetic Intermediates:

As a key intermediate in the production of cresyl trisiloxane (Mexoryl SX), it is used in the preparation of sunscreen cosmetics.
